Detection system and method for elevator door shielding behavior based on video analysis

Abstract

The invention provides a detection system for the elevator door shielding behavior based on video analysis. The detection system comprises a video collection unit, a door state analyzing unit, an alarm logistic unit and a multimedia prompting unit. The invention further provides a detection method for the elevator door shielding behavior based on video analysis, and the above system is adopted inthe detection method. The detection method includes the steps that a marker is stuck; information of the marker position on an elevator door is collected; the state of the elevator door is analyzed and judged; whether the door shielding behavior exists or not is judged; and a reminding broadcast is played. By means of the detection system and the detection method, an area collection manner is adopted, in addition, the set collecting area is calibrated in a tag manner so that the collecting boundary can be more obvious and is more accurate compared with the background, interference of the edgeof the elevator door and background shielding objects is avoided, and the detection accuracy is improved.

Description

technical field [0001] The invention relates to the technical field of video detection and the technical field of elevator safety. Background technique [0002] The behavior of the elevator blocking the door occurs from time to time, which seriously endangers the safe operation of the elevator. In the current elevator accidents, a large part is caused by the blocking door. In addition, some residents lack the common sense of elevator safety and use various objects to block the doors, even including baby carriages (with sleeping children in them). Little do they know that this poses a huge safety hazard. Once the elevator doors are forcibly closed, the consequences will be disastrous. [0003] At present, there have been researches on the behavior of elevator blocking doors. For example, Chinese patent application CN201710369596.6 discloses a method for detecting elevator door opening and closing based on camera images. The detection method uses elevator door boundary informa...

In addition, some residents lack the common sense of elevator safety, and use various objects to block the door, even baby carriages (with sleeping children in the car), but they do not know that there is a huge potential safety hazard. Once the elevator doors are forcibly closed, the consequences will be disastrous

[0003] At present, there has been research on the behavior of elevators blocking doors. For example, Chinese patent application CN201710369596.6 discloses a method for detecting elevator doors opening and closing based on camera images. This detection method uses elevator door boundary information to detect elevator doors. The original image The fusion of boundary features and binary image boundary features has the characteristics of fast calculation speed, real-time performance, stability and accuracy, but this method relies on edge detection, and the edges of the advertising stickers on the door and the background edges outside the door after opening have It may conform to the characteristics of the tilt angle, and the elevator door boundary is easily disturbed, which is prone to analysis errors
